ループ内のCSVファイル内の2つの単語列のトークン数を計算する方法は？

ソリューションは代わりにawkを使用します。出力には注意名のみを含める必要があるという質問で理解しました。以前の答えはより便利な出力を提供し、OPはその答えを受け入れ、スクリプトは同じ形式と同じデータセットに従います。

{
    x = $0
    gsub(/,/, " ", $0)
    a[x]=NF

}

END {
    for (key in a) {
        counter[a[key]] += 1
    }

    for (c in counter) {
        print counter[c] " values with " c " tokens:"
        for (key in a) {
            if (c == a[key]) {
                print "\t"key
            }
        }
    }
}
